WINDOW-SCREEN.

window. Briefly this type of window coma prises a pair of sashes capable of being bodily raised and lowered between the jambs of the window frame, the upper sash being provided at its bottom with means for pivotal engagement with the jambs, and a balance lever pivoted between its end to the frame and at its ends to the upper andlower sashes respectively. For a detailed descrip-' tion of the Austral window-sometimes called a. balanced windowreference is made to the U. S. patent to Knox 821,510, granted May 22nd, 1906, and the patent to Abell 12,408,. reissued November 14th, 1905.

The chief object of the invention is to provide a construction in which screens may be applied to and entirely removed from a standard window without in any way affecting the joint at the meeting rail of the sashes, and avoiding of course the necessity of the use of a filler or connecting pieces between the two meeting rails of the sashes when the screens are removed.

In the drawings: Figure 1 is a vertical section taken through an Austral window in open position and to which the preferred embodiment of my invention is applied. Fig. 2 is a detail section showing the meeting rails of the sashes in closed position. Fig. 3 is a section similar to Fig. 2 of a modified form of the invention.

Referring to the drawings in detail, in which like characters refer to the same parts in all the views, the reference numerals 10 and 11 designate the upper and lower sashes respectively, of a window which is located in a suitable frame 12. These sashes are provided with meeting rails 13 and 14 and are pivotally connected at 15 and 16 to balance arms 17, and the latter is pivotally connected, as indicated at 18, to the frame or jamb 12 as is well understood. The upper and lower screens 22 and 23 respectively.

In screening a window of this character there must necessarily be some sort of connection between the upper and lower screens. In case the screens are located on the opposite sides of the parting strips as distinguished from being located in the same plane, the lower end of the upper screen ends preferably just above themeeting rail of the lower sash while the upper end of the lower screen ends just below the meeting rail of the upper sash. As a result of this construction there is a considerable gap between the adjacent ends of the screens and it is the object of this particular inventionto bridge the space by means, positioned between the meeting rails of the sashes, which may be applied to and removed from the window without in any way affecting the normal position of the meeting rails of the sashes. In other words when the screens are removed from the window the meeting rails of the sashes contact with each other to form a closed joint without the necessity of providing a false filler for this purpose. To this end the upper screen, referring to Figs. 1 and 2, is provided with a metallic connecting piece 24 provided with a portion thatex tends downwardly to the space 25, which space is defined by the meeting edges of the meeting rails. The lower screen is pro- Fig. 3 illustrates a slightly modified form of the invention in which the metallic con-' necting pieces 24: and 26 are connected to the parting strip or some other portion of the jamb instead of being connected directly to the screens.

I WVhat I claim is:

1. In combination with a window frame, of a pair of balanced sashes capable of being raised and lowered simultaneously in said frame, parting strips for said sashes, upper and lower screens for said window frame in contact with but located on the opposite sides of said parting strip, and means for bridging the space between the lower end of the upper screen and the upper end of the lower screen comprising thin metallic members secured to said ends of the screen and connected to each other in a recess defined by the meeting edges of the meeting rails.

2. In combination with a windowframe, provided with a parting strip, of a pair of balanced sashes capable of being raised and lowered simultaneously in said frame and located on the opposite sides of said parting strip, upper and lower screens for said window located on the opposite sides of said Copies of this patent may be obtained for parting strip but in the reverse order from the sashes, and means for bridging the space between the lower end of the upper screen and the upper end of the lower screen comprising thin metallic members connected to each other in a recess defined by the meeting edges of the meeting rails.

3. In combination with a window frame provided with a parting strip, of a pair of balanced sashes capable of being raised and lowered simultaneously in said frame and located on the opposite sides of said parting strip, said sashes having meeting rails the meeting edges of which, in normal position, define an opening or recess, upper and lower screens for said window in contact with said parting strip the adjacent ends of which are separated from each other a distance equal to the vertical thickness of the meeting rails of the sashes, and means for bridging the space between the adjacent ends of the screens comprising metallic strips connected to each other in the recess defined by the meeting rails of the sashes.

In testimony whereof I hereunto afliX my signature.
